sibai1 on 01 Apr 25Due to the high toughness, high thermal strength and low thermal conductivity of stainless steel materials, the deformation during cutting is relatively large, and the hardening during process is serious. The more to cut, the more difficult it is to dissipate heat, resulting in a rapid increase in the temperature of the tool tip, resulting in built-up edge. The built-up edge can easily take away the coating on the tool tip itself, aggravate the wear of the tool, affect the roughness of the tool surface, and also affect the surface quality of the workpiece.
